OWC 256GB DDR4 3200 CL22 8Rx4 288-pin 1.2V ECC Registered RDIMM memory upgrade
A 256GB DDR4 3200 ECC Registered RDIMM upgrade for Cisco UCS C240 M6, C245 M6, B480 M5, C220 M5 and C240 M5 servers
Capacity 256GB
- 256GB single module maximises server capacity
- DDR4 3200 speed accelerates data throughput
- CL22 latency ensures responsive multitasking
- 2V operation reduces power consumption
- ECC Registered design protects data integrity
Server-grade capacity
This single module delivers 256GB of DDR4 memory in a registered ECC configuration. It is built for Cisco UCS servers including the C240 M6, C245 M6, B480 M5, C220 M5 and C240 M5. The octal-rank design requires a platform that supports 8Rx4 modules and will not work in standard desktop computers or alongside unbuffered or load-reduced DIMMs.
Thermals and power profile
Operating at 1.2V, the DIMM conforms to the standard DDR4 voltage envelope for registered server memory. JEDEC compliance and RoHS adherence indicate a design validated for continuous operation in densely populated server chassis. No active cooling is present on the module itself; thermal management relies on the host system's airflow.
Sustained load behaviour
The CL22 latency at 3200 MT/s provides predictable timing for memory-bound workloads such as virtualisation, in-memory databases and large-scale analytics. Registered buffering reduces electrical loading on the memory controller, helping maintain signal integrity when all slots are populated. ECC circuitry detects and corrects single-bit errors throughout extended duty cycles.

Ερωτήσεις για αυτό το προϊόν
How do I install this 288-pin RDIMM in a Cisco UCS C240 M6, and what step is often missed?
Power down the server, open the chassis, align the notch on the 288-pin DDR4 module with the slot key, press firmly until both ejector tabs click, then verify in BIOS that all 256GB are recognised at 3200 MT/s.
What maintenance or replacement will this ECC Registered module need over its service life?
No scheduled maintenance is required; the module is validated to JEDEC DDR4 standards and covered by a limited lifetime warranty, so replacement only occurs if a correctable error count exceeds the platform threshold.
What limit appears first when this 8Rx4 256GB DIMM runs sustained workloads at 3200 MT/s?
The octal-rank 8Rx4 organisation increases electrical loading on the memory bus, so the platform typically reaches its maximum DIMM-per-channel limit before thermal or bandwidth constraints become an issue.
